Furse Earthing and Lightning Protection
and Electronic Systems Protection by Thomas & Betts
RF Systems Using Coaxial
Cables at frequencies between DC & 2.7GHz
 The
standard RF protector offers a cost effective protection
solution for use on coaxial cables to protect RF transmitter and
receiver systems, including electronics located at the antenna
or dish. Typical examples include cell sites, military
communications, satellite earth stations and pager systems.
-
Restricts
let-through voltage below damage levels of interface
circuitry
-
Very low
attenuation and near unity VSWR over a wide range of
frequencies ensure the protectors do not impair systems
performance
-
Wide bandwidth
means a single product is suitable for a range of
applications, including the transmission of DC power
-
Easily mounted
and earthed via fixtures on the base of the unit
-
Available with
N, 7/16 DIN and BNC connectors
-
Robust silver
plated aluminium housing

Higher Specification RF
Systems Using Coaxial Cables at frequencies between 50MHz &
2.7GHz
 Use
on coaxial cables to protect RF transmitter and receiver
systems, including electronics located at the antenna or dish.
Typical examples include cell sites, military communications,
satellite earth stations, pager systems and emergency services
communications systems.
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
-
Superior
transient protection to both Gas Discharge Tube (GDT) and
Quarter Wave Stub (QWS) based protectors
-
Full mode design
capable of handling partial lightning currents as well as
allowing continual operation of protected equipment
-
Wide bandwidth
means a single product is suitable for a range of
applications
-
Available with
N, 7/16 DIN and BNC connectors
-
Easily mounted
and earthed via fixtures on the base of the unit that accept
M3 and M5 screws or via mounting brackets

CCTV Video Lines
 Use
these protectors on the video cable to outdoor CCTV cameras and
central control and monitoring equipment. Suitable for coaxial
CCTV cables with BNC connectors (ESP CCTV/B) or twisted pair
CCTV lines (ESP CCTV/T) on systems with either an earthed or an
isolated screen. Not suitable for use on broadcast, satellite or
cable TV systems.
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all lines - Full Mode protection
-
Full mode design
capable of handling partial lightning currents as well as
allowing continual operation of protected equipment
-
100MHz bandwidth
prevents the degradation of high frequency signals
-
Low in-line
resistance to minimise unnecessary reductions in signal
strength and maximise signalling distance
-
Suitable for
either earthed or isolated screen systems
-
ESP CCTV/B has
Network Rail Approval PA05/02510. NRS PADS reference
086/023410

SSI Mains Power Supplies
& Data Links
 To
prevent transient overvoltage damage to Solid State Interlocking
(SSI) systems, protectors should be fitted in trackside cabinets
and equipment rooms, on both the data link and the mains power
lines.
-
Accepted for use
on Network Rail infrastructure
-
Very low
let-through voltage (enhanced protection to BS EN 62305)
between all sets of conductors - Full Mode Protection (ESP
SSI/120AC and ESP SSI/140AC) and all signal lines (ESP
SSI/M)
-
ESP SSI/B
modified base unit can be permanently wired into the system
-
ESP SSI/M
plug-in protection module can be replaced without
interfering with the operation of the system
-
ESP SSI/B
incorporates a 100Ω terminating resistance that can be
connected if required
-
ESP SSI/120AC
and ESP SSI/140AC are a compact size for easy installation
in trackside cabinets and control rooms
-
All products
have Network Rail Certificates of Acceptance, allowing them
to be used on Network Rail infrastructure
